Where exactly is this plant treasure hub? When Colonel Robert Kid in 1787 started the famous botanical gardens in Shibpur, William Roxburgh was appointed as the first garden superintendent between 1793-1814. The building was thus named after him and constructed around 1794. In the beginning this sprawling building acted as a residence for Roxburgh, but he constructed a plant house and a library to carry on pioneering work in plant studies from here. His famous book “Flora Indica” was once considered as the bible for botanists and researchers interested in Indian flora.
